Next, the operation of the lighting device 10 will be explained.

To newly install the lighting device 10, pull the power wire 33 drawn out from the ceiling into the main body 11 through the wiring hole 25, connect it to the terminal block 17, and attach the main body 11 to the hanging bolt 26. Install it on the ceiling.

Hook the mounting spring 45 of the light source unit 12 onto the spring holder 18 of the main body section 11, and connect the connector 49 of the connection cable 50 on the light source unit 12 side to the connector 29 of the output cable 30 led out from the power supply section 16 of the main body section 11. Connecting. The light source unit 12 is pulled up to the main body part 11 by the spring force of the attachment spring 45, and the light source unit 12 is attached to the main body part 11.

Furthermore, if an existing lighting device of the same type as the lighting device 10 but not including the auxiliary device section 37 is installed on the ceiling, it can be replaced with the light source unit 12 including the auxiliary device section 37. In this case, the existing light source unit of the existing lighting device is removed from the existing main body, that is, the main body 11, and the light source unit 12 is electrically connected and attached to the main body 11 as described above.

Then, when power is supplied to the lighting device 10 from the external power supply, the power supply unit 16 converts the power from the external power supply into lighting power and supplies it to the light source unit 36. In the light source section 36 to which lighting power is supplied, the light emitting element 48 lights up, and the light from the light emitting element 48 passes through the light source cover 44 and is irradiated into the illumination space.

The voltage conversion unit 43 provided in the light source unit 36 converts the lighting power supplied from the power supply unit 16 to the light source unit 36 into operating power of a predetermined voltage to be supplied to the auxiliary equipment unit 37, and converts the lighting power supplied to the light source unit 36 from the power supply unit 16 into operating power of a predetermined voltage to be supplied to the auxiliary equipment unit 37. It is supplied to the camera 54 of the equipment section 37.

The camera 54 to which operating power has been supplied takes an image using its image sensor and stores the taken image or video in the storage unit.

At this time, if the light from the light source section 36 enters the camera 54 side, the light will be reflected in the image taken by the camera 54. Therefore, the light entering the camera 54 side from the light source section 36 is blocked, and the above-mentioned influence on photography by the camera 54 is prevented.

Furthermore, when the outer surface side of the light shielding section 57 is formed as a reflective surface, the light from the light source section 36 is reflected on the reflective surface, and the light directed toward the auxiliary equipment section 37 can be effectively used, thereby improving lighting efficiency. .

Furthermore, by wirelessly connecting a communication terminal to the camera 54 and operating the communication terminal, it is possible to check the video stored in the storage section of the camera 54 on the communication terminal and to acquire video data to the communication terminal.

Generally, the life of the camera 54 is shorter than the life of the light emitting element 48 of the light source section 36. At the end of the life of the camera 54, only the auxiliary equipment section 37 is replaced, and the light source section 36 continues to be used. Note that even if the camera 54 breaks down, only the auxiliary equipment section 37 is replaced, and the light source section 36 continues to be used.

When replacing the auxiliary equipment section 37, pull the light source unit 12 down from the main body 11 against the spring force of the mounting spring 45, and connect the connector 49 of the connection cable 50 on the light source unit 12 side to the output cable on the main body 11 side. 30 from the connector 29, remove the mounting spring 45 of the light source unit 12 from the spring holder 18, and remove the light source unit 12 from the main body 11.

Release the mechanical locking by the connection connection part 38, remove the second connection connection part 38b of the auxiliary equipment part 37 from the first connection connection part 38a of the light source part 36, and disconnect the auxiliary equipment part 37 from the light source part 36. Remove.

The new auxiliary equipment section 37 is mechanically and electrically attached to the light source section 36 at the connection connection section 38, and the light source unit 12 is attached to the main body section 11 as described above.

Note that the auxiliary equipment section 37 may be replaced while the light source unit 12 is pulled down from the main body section 11 against the spring force of the mounting spring 45.

Further, when the light source section 36 reaches the end of its lifespan or breaks down, only the light source section 36 may be replaced and the auxiliary equipment section 37 may be continued to be used.

According to the light source unit 12 of the present embodiment, when an existing lighting device that is of the same type as the lighting device 10 and does not include the auxiliary device section 37 is installed on the ceiling surface, the light source unit 12 that includes the auxiliary device section 37 It can be operated by replacing it with.

Moreover, since the auxiliary equipment section 37 is removably connected and electrically connected to the longitudinal end side of the light source section 36 by the connection connection section 38, one of the light source section 36 and the auxiliary equipment section 37 will reach the end of its lifespan. When this is reached, it becomes possible to replace only one and continue to use the other, allowing the light source section 36 and the auxiliary equipment section 37 to be used effectively until their respective lifetimes. Further, the same applies when one of the light source section 36 and the auxiliary equipment section 37 is out of order.

Furthermore, the connecting part 38 enables mechanical and electrical connection between the light source part 36 and the auxiliary equipment part 37, thereby facilitating the replacement of the auxiliary equipment part 37 or the light source part 36. I can do it.

Further, since the light source section 36 includes the voltage conversion section 43, the power supplied to the light source section 36 can be converted into voltage and supplied to the auxiliary equipment section 37.

Furthermore, even when the light source section 36 has the voltage conversion section 43, by providing the voltage conversion section 43 on the substrate 47 on which the light emitting element 48 is mounted, it is possible to reduce the size and complexity of the light source section 36.

Furthermore, in the case of a device such as a camera 54 that is easily affected by light from the light source section 36, the auxiliary device section 37 has a light blocking section 57 disposed between the light source section 36 and the light source section 36. It can reduce the influence of light from

In addition, in the light source unit 12, the length of the light source section 36 is shorter than that of the existing light source unit, so in order to ensure the same brightness as the existing light source unit, the pitch of the light emitting elements 48 mounted on the board 47 must be shortened. It is necessary to do so, but it will increase the glare. On the other hand, it is desirable that the camera 54 of the auxiliary equipment section 37 be able to capture clear images. On the other hand, in the light source unit 12, the light source section 36 and the auxiliary equipment section 37 are separated, so the light source cover 44 of the light source section 36 has light diffusing properties to reduce glare, and the auxiliary equipment This can be achieved by making the auxiliary cover 56 of the section 37 transparent so that the camera 54 can take a clear image.

Note that the device main body of the auxiliary device section 37 is not limited to the camera 54, and may be other devices such as an auxiliary light source such as a spotlight, a sensor such as a human sensor or a brightness sensor, a speaker, a communication unit, etc.

Further, the configuration of the light source unit 12 is applicable not only to a direct-mounted lighting device but also to a recessed lighting device, a hanging lighting device, and the like.
